Samsung is rolling out the Android 5.0.1 I9295XXUDPA4 Lollipop update for all the Samsung Galaxy S4 Active I9295 models.

Check the instructions listed in this post in order to learn how to successfully flash a new official Lollipop update manually for your phone. This new update comes with several bug fixes and some new features that will improve the overall performance of your Galaxy S4 Active device.

Before starting the installation of this new update you will need to make sure that your phone meets all required for such task.

Preparation Steps:

Use this tutorial only with the Samsung Galaxy S4 Active GT - I9295 devices.
Check the model of your phone under Settings> About Phone menu.

Do not attempt to update any other Galaxy S4 models with the files that you will find in this post.

Download the Samsung USB Drivers here and install them on your computer. The usb drivers will allow your computer to detect the phone and make sure that the update will complete successfully.

For the updating process you will need to use the Odin tool.
For Odin to work you need to disable the antivirus apps and the Samsung KIES from running on your PC. These types of apps will block Odin from sending any new firmware files to your Galaxy S4 Active device.

Enable USB Debugging on your phone from the Developer Options menu.
If the Developer Options menu is not listed under Settings, then you will have to enable it first: go to Settings> About Phone and tap seven times on the Build Number section.

Your phone can be rooted, but you need to know that the update will revoke any root access. Any custom Recovery will be replaced with a stock Recovery, too.

The official update can be flashed over a custom ROM, too. But, for your Galaxy S4 Active device to boot in normal mode after the update is installed over the custom ROM, then you will need to apply a 'factory reset' process.
The Factory Reset process is listed at the end of this post and you can apply it from Recovery Mode.

If your phone is running stock Android, then the 'factory reset' is not necessary and you won't lose any important data in the process.

Read the entire guide and do not skip any steps if you want to complete the update at your first attempt.

Check the battery charge level of your device and make sure that it is over 50%, as it will prevent the device from powering off during the Android 5.0.1 first boot process.

How to flash Android 5.0.1 I9295XXUDPA4 Official Update for Galaxy S4 Active I9295 using Odin:

Extract the archived contents of the firmware archive and save the file on your PC.
- the I9295XXUDPA4 tar.md5 file should be obtained after the file is unzipped.
- do not extract any further than that.

Use the usb cable and connect your phone to your PC.
- now you have to check Odin main screen and wait for it to add your phone.
- if the phone is not detected you need to reinstall the Samsung usb drivers.

Go back to Odin and disable the 'Re-Partition' option.
- if 're-partition' is disabled already, then you can skip this step.

Click on the AP button in Odin.

Locate and load the I9295XXUDPA4 Lollipop tar.md5 file in ODIN.

Hit the START button in order to initiate the Android 5.0.1 update process.
- don't press any buttons until the installation is done.

When the update is complete you will see the PASS alert shown by Odin and the phone will reboot in normal mode.
- note that the first boot process of this new official ROM is going to take a while before it is done.

Use your usual login data in order to regain control over your phone.

NOTE 1:

If Odin shows the FAIL alert or the installation freezes at some point, then you need to repeat the whole process once again.

If you try to repeat installation, then you need to re-read the preparation steps and to make sure that your Galaxy S4 Active device meets all requirements. Also, make sure not to skip any steps.

NOTE 2:

If the Android 5.0.1 first boot process takes too long to finish, or the phone enters in a boot loop, then you need to factory reset the phone.

The factory reset has to be applied by those that have installed the update over a custom ROM, too. Here's how to do that:

Power off the phone and boot it in Recovery Mode. Select 'wipe data/ factory reset' and confirm process. Reboot in normal mode and you're done with this update.
